Hi. Well, I got a dark brown blood flowing in the mid of the cycle. The flow is lighter in intensity but enough to use sanitary napkins. Also my usual period duration is 2 to 3 days. But its the fifth day that dark brown discharge is not stopping. For additional info i started indulging in sexual activities just 2 months back. But i hardly had intercourse for about 4 times and took birth control pill twice to be on safer side. And just a week before i got this midcycle discharge i had the pill. I have never had any abnormalties in my cycle. Whats the reason for this ? Could this be any infection or just hormonal imabalance. ? Can i be pregnant by any chance though its not really possible considering the precautions and number of times we had. Please help me. Could this be nay sign of pregnancy too ??
